- addon anti spam
- adds in the right click on player's link, the choice: To ignore line
- puts in lower case the line, and takes away all space
- if this line is seen again, she is not any more shown
- memorize 30 minutes of chat during which you can ignore certain lines
- if a line is never reread (and therefore concealed) during month, it will be taken away of the concealed lines, if they come back, you will once again have to conceal them
- also work for the addon: ChatMondialServeur
- no adjournment for spam is sent in blizzard, these lines are fair steps shown
